Installation & Usage
npm & ESM
npm i echarts vue-echarts
To make vue-echarts
work for Vue 2 (<2.7.0), you need to have @vue/composition-api
installed (@vue/runtime-core
for TypeScript support):
npm i @vue/composition-api npm i @vue/runtime-core # for TypeScript support
If you are using NuxtJS on top of Vue 2, you'll need @nuxtjs/composition-api
:
npm i @nuxtjs/composition-api
And then add '@nuxtjs/composition-api/module'
in the buildModules
option in your nuxt.config.js
.
Example
Vue 3 Demo β
Vue 2 Demo β
Important
We encourage manually importing components and charts from ECharts for smaller bundle size. We've built an import code generator to help you with that. You can just paste in your option
code and we'll generate the precise import code for you.
But if you really want to import the whole ECharts bundle without having to import modules manually, just add this in your code:
CDN & Global variable
Drop <script>
inside your HTML file and access the component via window.VueECharts
.
Vue 3 Demo β
const app = Vue.createApp(...)
// register globally (or you can do it locally) app.component('v-chart', VueECharts)
Vue 2 Demo β
// register globally (or you can do it locally) Vue.component("v-chart", VueECharts);
See more examples here.
Props
init-options: object
Optional chart init configurations. Seeecharts.init
'sopts
parameter here β
Injection key:INIT_OPTIONS_KEY
.theme: string | object
Theme to be applied. Seeecharts.init
'stheme
parameter here β
Injection key:THEME_KEY
.option: object
ECharts' universal interface. Modifying this prop will trigger ECharts'setOption
method. Read more here βπ‘ When
update-options
is not specified,notMerge: false
will be specified by default when thesetOption
method is called if theoption
object is modified directly and the reference remains unchanged; otherwise, if a new reference is bound tooption
,notMerge: true
will be specified.update-options: object
Options for updating chart option. SeeechartsInstance.setOption
'sopts
parameter here β
Injection key:UPDATE_OPTIONS_KEY
.group: string
Group name to be used in chart connection. SeeechartsInstance.group
here βautoresize: boolean | { throttle?: number, onResize?: () => void }
(default:false
)
Whether the chart should be resized automatically whenever its root is resized. Use the options object to specify a custom throttle delay (in milliseconds) and/or an extra resize callback function.loading: boolean
(default:false
)
Whether the chart is in loading state.loading-options: object
Configuration item of loading animation. SeeechartsInstance.showLoading
'sopts
parameter here β
Injection key:LOADING_OPTIONS_KEY
.manual-update: boolean
(default:false
)
For performance critical scenarios (having a large dataset) we'd better bypass Vue's reactivity system foroption
prop. By specifyingmanual-update
prop withtrue
and not providingoption
prop, the dataset won't be watched any more. After doing so, you need to retrieve the component instance withref
and manually callsetOption
method to update the chart.
Events
You can bind events with Vue's v-on
directive.
Note
Only the
.once
event modifier is supported as other modifiers are tightly coupled with the DOM event system.
Vue-ECharts support the following events:
highlight
βdownplay
βselectchanged
βlegendselectchanged
βlegendselected
βlegendunselected
βlegendselectall
βlegendinverseselect
βlegendscroll
βdatazoom
βdatarangeselected
βtimelinechanged
βtimelineplaychanged
βrestore
βdataviewchanged
βmagictypechanged
βgeoselectchanged
βgeoselected
βgeounselected
βaxisareaselected
βbrush
βbrushEnd
βbrushselected
βglobalcursortaken
βrendered
βfinished
β- Mouse events
- ZRender events
zr:click
zr:mousedown
zr:mouseup
zr:mousewheel
zr:dblclick
zr:contextmenu
See supported events here β
Native DOM Events
As Vue-ECharts binds events to the ECharts instance by default, there is some caveat when using native DOM events. You need to prefix the event name with native:
to bind native DOM events (or you can use the .native
modifier in Vue 2, which is dropped in Vue 3).
Provide / Inject
Vue-ECharts provides provide/inject API for theme
, init-options
, update-options
and loading-options
to help configuring contextual options. eg. for init-options
you can use the provide API like this:
Vue 3
import { THEME_KEY } from 'vue-echarts' import { provide } from 'vue'
// composition API provide(THEME_KEY, 'dark')
// options API { provide: { [THEME_KEY]: 'dark' } }
Vue 2
import { THEME_KEY } from 'vue-echarts'
// in component options { provide: { [THEME_KEY]: 'dark' } }
Note
You need to provide an object for Vue 2 if you want to change it dynamically.
// in component options { data () { return { theme: { value: 'dark' } } }, provide () { return { [THEME_KEY]: this.theme } } }
Methods

Static Methods
Static methods can be accessed from echarts itself.
CSP: style-src
or style-src-elem
If you are applying a CSP to prevent inline <style>
injection, you need to use files from dist/csp
directory and include dist/csp/style.css
into your app manually.
Migration to v6
π‘ Please make sure to read the migration guide for ECharts 5 as well.
The following breaking changes are introduced in vue-echarts@6
:
Vue 2 support
- If you are using version prior to
vue@2.7.0
,@vue/composition-api
is required to be installed to use Vue-ECharts with Vue 2 (and also@vue/runtime-core
for TypeScript support).
Props
options
is renamed tooption
to align with ECharts itself.- Updating
option
will respectupdate-options
configs instead of checking reference change. watch-shallow
is removed. Usemanual-update
for performance critical scenarios.
Methods
mergeOptions
is renamed tosetOption
to align with ECharts itself.showLoading
andhideLoading
is removed. Use theloading
andloading-options
props instead.appendData
is removed. (Due to ECharts 5's breaking change.)- All static methods are removed from
vue-echarts
. Use those methods fromecharts
directly.
Computed getters
- Computed getters (
width
,height
,isDisposed
andcomputedOptions
) are removed. Use thegetWidth
,getHeight
,isDisposed
andgetOption
methods instead.
Styles
- Now the root element of the component have
100%Γ100%
size by default, instead of600Γ400
.
